%X purpose: the objective of this study was to evaluate the use of the sugarcane biopolymer membrane in femoral artery patch angioplasty on dogs. methods: eight dogs were submitted to bilateral femoral artery patch angioplasty with a sugarcane biopolymer membrane patch on one side and e-ptfe patch on the contralateral side. this research was performed at experimental surgical research laboratory of the centro de ci¨ºncias da sa¨²de at universidade federal de pernambuco. the dogs were submitted to a new surgery at 180 days after the patch angioplasty in order to harvest the femoral artery. all the animals were evaluated by: clinical examination, measure of femoral artery diameter, arteriogram and doppler fluxometry. yet the material harvested was sent to histological study. each animal served as its own control. results: in all vessels of both groups there were no cases of infection, aneurysm formation, rupture or pseudoaneurysm formation and thrombosis. in both groups it was observed a chronic inflammatory reaction with lymphocytes, neutrophils and fibrosis in the outer surface of the patches. it was observed fibrosis in the inner surfaces of all the patches. in e-ptfe patches occurred invasion by fibroblasts. conclusion: the sugarcane biopolymer membrane can be used as a patch in femoral artery angioplasty on dogs.
